Remunan
Naming Traditions
Most Remunans have three names. The first name is the personal name given by the person's parents. It is used in everyday situations.
The second name is usually a family name. In some cases it can also refer to the person's heritage. One of the group which uses such names are foreigners.
The third name can have multiple purposes. It can be a nickname or an augmentation of the first or second name. As an augmentation it is used to identify a specific person or branch in the family.
Culture
Major language groups and dialects
All Remunans speak the same language, but due to the size of the territory they live in there is a lot of local dialects. The core language comes from the city Remun, the culture's legendary birthplace. The Remun dialect is still the closest to the original language.
Common Dress code
Most Remunans wear simple woolen or linen tunics. In most cases male ones end just above the knee and the female ones go all the way to the feet. All tunics are fastened with a leather belt placed around the hips.
The nobility wears more decorative tunics with symbols of their families and any offices they hold. During social events and ceremonies nobles wear togas which are draped over the shoulders and around the body. Togas are worn over a tunic. Most togas are white. The only people allowed to wear togas in different colours are the Tetrarchs Their togas are purple, which is the royal colour.
I really like the idea of a Bulla. :D Nice overview of the ethnicity here.
